Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications[1] and the integration of telecommunications(telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage, and audiovisual systems, that enable users to access, store, transmit, and manipulate information.
TYPES OF ICT

type of ICT system is focused on
managing data and information.
For examples: these are a sports club membership system or a supermarket stock
system.
Control systems: These ICT systems
are mostly part to control machines. They use input, process
and output, but the output may be moving a robot arm to weld a car chassis
rather than information.
Communications systems: The
output of these ICT systems is the successful transport of data from
one place to another.
